I have a three CM cluster using 3.3(3)sr4a. The phones are either 7940's or 7960's. For testing purposes, I am trying to get just one phone to register on what would normally be a "backup" CM. I know one can assign static IP addresses, etc. But I don't see the option to force the first CM to a specific server. Anyone have any ideas if/how to do this?
We created three different call manager groups and added all three call managers to each group. The call manager were listed in a prioritized order within each group. We then created three device pools and referenced the appropriate call manager group for each device pool. We then referenced the appropriate device pool for each phone.
